We are pleased to introduce our two larger junction boxes:
- 1532 Series – 7-7/8” long x 2-3/8” tall x 1-5/8” deep, offering an inside volume of close to 32 cu.in.
- 1432 Series – 7-7/8” long x 4” tall x 2” deep, with almost 64 cu.in.
By contrast our 1232 series junction box measures 4-3/4” long x 3” tall x 1-3/4” deep at only 25 cu.in.

32 cu. in J-Boxes (L: 1532-10 & components, R: 1532T)

64 cu. in. J-Boxes (L: 1432-10 & components, R: 1432T)
Both series come in three versions:
- Z-Bracket: Contains our proven Z-Bracket to offset the J-Box and elevate it by 1”, ready to be riveted directly to most of our plaster frames – Part #1532 & #1432
- Flat: Ready to be riveted directly onto the top side of most of our plaster frames, for reduced height. – Part #1532-10 & #1432-10
- TWIST™: Comes with our proven Z-Bracket riveted to one end, and a stop means at the other, allowing the box to be rotated in either direction! – Part #1532T & #1432T
This facilitates:
- line voltage installation by the electrician
- improved servicing access by rotating it toward the ceiling opening
- servicing in very small ceiling openings (2-3/4” or 70mm) where a hand can’t fit. Use the #1532T Twist 32 with its 2-1/2” wide cover; simply pull the luminaire cable or hook a bent coat hanger wire onto the T-wing and pull to rotate the Twist until the free end is over the hole, where the cover may be unlatched and lowered. Sure beats busting the ceiling for servicing!

The correspondingly long J-Box covers 1542 & 1442 measure 8”, accommodating longer drivers, and are available with whatever driver mounting and wire passage hole configuration is required. Both J-Boxes contain multiple knockout holes; 9/16”, 7/8” & 1-1/8”. Made of galvanized steel, .05” min thickness to comply with UL1598.
Optional slide-in dividers (with integral strain relief slot to permit wire passage) are available for line and low voltage separation, and can be placed in four positions; 1-1/2”, 2”, 2-1/2” & 3” from each end.
